CHARLES A. DUPREZ, or REIMS, FRANCE.

IMPROVEM ENT IN APPARATUS FOR SEPARATING BURGEONS 0R GERMS FROM GRAIN.

Specification forming part of Letters Patent No. 186,328, dated January 16, 1877; application filed November 4, 1876.

To all whom it may concern:

Be it known that 1, CHARLES ANTOINE DUPREZ, of Reims, in the Republic of France, have invented certain new and useful Improvements in Apparatus for Separating Burgeons, or Germs, or Sprouts from Grain, of which the following is a specification My invention has for its object the employment, in machines or apparatus for separating burgeons or sprouts, or other foreign bodies adhering to grain, of brushes, arranged either vertically or horizontally, but actuated to have a reciprocating movement, and arranged so as to receive the grain to be cleansed between them, in order to remove therefrom by friction the germs or sprouts which adhere thereto.

My machine, besides other advantages, which will hereafter more fully appear, may be arranged, as shown, to occupy but little space, and requires to be driven with less power than any machine to me known.

Referring to the drawing, which represents my machine, Figures 1 and 2 are, respectively, side and front elevations of the same. 7

The apparatus, as shown, consists ofa frame, A, carrying at its upper part a shaft, B, upon which are mounteda loose and fast-pulley, D and E, also the fly wheel F and movementtransmitting pulley G. The shaft within the compass of the frame is provided with, or bent to form, two cranks, which give movement to connecting-rods H, to whose lower ends are attached brushes I, which, according to the position of the cranks, have movements in opposite directions, so that while one descends the other ascends, and vice versa. To the up per part of the frame is secured, by means of supports or brackets K, a hopper, L, which terminatesat its lower end in a conical conduit, L. Underneath the brushes, and attached to the frame, is arranged an inclined sieve, M, or an analogous apparatus, made of perforated sheet-iron or wire-gauze. To this sieve a short and quickly-reciprocating movement is imparted by means of the crank N and its connecting-rod. By this means the grain is allowed to fall into a special reservoir, where it is collected to be taken therefrom for subsequent operations.

The apparatus thus arranged is intended to operate as follows: The grain which is to be cleansed is put into the hopper L,-whence it is conveyed, by means of the conduit L", to the brushes I, the back-and-forth or up-and-down I claim, and desire to secure by Letters Patent,

The combination, in machines for separating from grain germs or sprouts, or other foreign bodies which adhere, or may adhere, to it,'of brushes arranged in pairs, and actuated to have a reciprocating movement relatively to each other, with conduit or conduits to convey the grain to be cleansed between said brushes, allsubstantial] y as herein set forth.

In testimony whereof l have signed my name to this specification before two subscribing witnesses.

DUPREZ. [L.. s.]
